To solve the question of which drug cannot be used clinically to help a patient cope with depression and insomnia, we will analyze each option provided.

### Step-by-Step Solution:

1. **Understanding the Question**:
- We need to identify which drug among the given options is not used clinically for treating depression and insomnia.

2. **Analyzing Each Option**:
- **Barbiturates**: These are central nervous system depressants that can be used to treat anxiety and insomnia. They are not commonly used today due to their potential for addiction and overdose, but they can still be used in certain clinical situations.
- **Amphetamines**: These are stimulants that increase alertness and energy. They are not used to treat depression or insomnia; in fact, they can exacerbate insomnia and are typically used to treat conditions like ADHD.
- **Benzodiazepines**: These are also central nervous system depressants that are commonly prescribed for anxiety and insomnia. They help patients relax and sleep, making them suitable for treating these conditions.
- **Cocaine**: This is a powerful stimulant derived from the coca plant. It has no clinical use for treating depression or insomnia and is known for its addictive properties and negative effects on mental health.

3. **Identifying the Correct Answer**:
- Among the options, **Amphetamines** and **Cocaine** are not used to treat depression and insomnia. However, cocaine is the most inappropriate choice as it is not used clinically for these conditions at all.

4. **Conclusion**:
